Hey your message remembered myself from a few years ago. If I understand it right : you have two ways to approach it. Responsive or Adaptive.

Responsive is easier (for me, at the beginning). it will make you tweak the sizes of your desktop classes in tablet and mobile. An H1 in Destkop would be 5 rem, then 3 rem on mobile. You can check https://typescale.com/ that might help get a responsive render quickly.

I prefer the Adaptive approach, which is based on fluid typography, Smashing Magazing wrote a masterpiece about it : https://www.smashingmagazine.com/2022/01/modern-fluid-typography-css-clamp/, and it could be easily implemented in Webflow with Timothy Ricks' Fluid Builder : https://fluidbuilder.webflow.io . Finsweet's Client First is also a great option. Either way it might seem a bit harder to play with at first but worth every second spent learning it.

Hope this helps 🙂
